STEAM-SEPARATOR.

SPECIFICATION forming part of Letters PatentNO. 768,190, a d August 28, 1904. Application filed August 17, 1903. Serial No. 169,707. (No model.)

To (1 7 7 whom, it may concern.-

Be it known that I, JAMES N AYLOR Jr. ,acitizen of the United States, residing atiirlington, in the county of Hudson and State of New Jer sey, have invented certain new and useful Improvements in Steam-Separators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a separator for the separation of the steam from its excessive moisture and the conducting of the dry steam and water therefrom in different directions, and has for its object to give to the inflowing steam an unobstructed whirling movement and permit it to move forward constantly to the outlet unimpeded, so as to thoroughly accomplish the separation.

M y invention consists, essentially, in a shell of suitable size provided with a steam-inlet and a wateroutlet. Adjacent to the steam-inlet is arranged a deflecting-plate to divide up the inflowing steam and deliver it with a whirling movement, but with an unimpeded flow, through a series of passages (larger in total area than the area of the steam-inlet) into an upper chamber. Centrally in this upper chamber and as near as possible to the steam-inlet, but on the opposite side of the deflecting-plate from the inlet, is arranged the steam-outlet pipe having its center arranged substantially to correspond with the center of the whirl. A dividing-plate is-arranged within the shell to divide it into the upper or whirling chamber and the lower or still chamber. The dividing-plate is preferablyprovided with a series of sharp edges, which, so to speak, peel off the water from the steam, permitting the water to pass quickly through or around the dividingplate into the still chamber.

.My invention is shown in the drawings herewith, in all the figures of which corresponding reference-numerals are used.

Figure I is an elevation of the vertical type.

of my separator with portions broken away. Fig. II is a top plan view of same with portions broken away. Fig. III is a cross-section on line III III of Fig. I. Fig. IV is a top plan of the dividing-plate. Fig. V is a vertical section of the horizontal type. Fig. VI is a vertical section of a modified form adapted for use inside a boiler. Fig. VII is a top plan thereof. Fig. VIII is a cross-section of Fig. VI on section-line VIII VIII.

In the figures, 1 indicates the cylindrical shell, to which is fitted the base 2, provided with a suitable water-outlet 3 and with the head 4, provided with the steam-inlet 5. To the head isseeured the deflecting-plate 6, having one or more knife-like edges 7 preferably formed, as here shown, vertical on one side and curved on the other with the straight downward curve 8. 10 indicates the integral walls, (connecting the deflecting-plate to the head, if desired,) arranged at right angles to each of said knife-edges and forming with the respective curved surfaces 8 the inletpassages 11. The outer edges of these walls 10 are curved, as here shown, in the arc of a circle whose radius is the same as that of the inlet. As shown in Figs. II and III, four inlet-passages are thus formed, the total area of whose'mouths is larger than the area of the inlet and by the form of the curved surfaces and the walls deliver the steam with a rotary motion and without obstructing its flow into the upper chamber 13. The deflecting-plate and walls may be conveniently cast integral with the head. Centrally in this chamber, so that its center will correspond practically with'the center of the whirl given to the steam in its vortex, is arranged the steam-outlet pipe 14, whose mouth is arranged as near as possible to the deflecting- "plate and the inlet-passages.

In any suitable manner is sustained within the shell the dividing-plate 20, dividing the interior into the whirling chamber 13 and the still'chamber 21, from the latter of which flows out the water to a steam-trap. The dividing-plate is ,'best shown in Fig. I adjustably secured on the steam-outlet pipe by the set-screw 23 in its hub and is provided with outwardly-extending lugs 24, provided with sharp edges 25, whose function is to cut or peel off, so to speak, the water from the whirling mass of steam, thus promoting and insuring the separation.

2 sEsTaasaAsiE cor The separator shown in Fig. V is the same as the preceding except that it is arranged horizontally and is provided with a T 26 for the water-outlet communicating with the supporting-column 27, through which the water flows out to the trap.

In Figs. VI, VII, and VIILI have shown myinvention embodied in a form for the interior of a boiler. Here the shell may be made much lighter, as it does not have to withstand steam-pressure, and the steam-inlet is arranged around the steam-outlet and concentrically therewith. 41 41 are end .plates for the shelhand with the top one is made integral the-special form of deflecting-plate 42,v

having radiating knife edge partitions or vanes 43, arranged tangentially, so as to give the inflowing steam its whirling motion. The dividing-plate is preferably fixed by means of its lugs at a special point in the interior. The steam-outlet pipe 46 is threaded into the defiectingplate and also at its outer end is threaded to engage with the shell of the boiler. The annular inlet 45 may be much greater in area than the outlet 46. At the lower end of the separator is arranged a balanced lever 47 and check 48 to close the water-outlet against the inflow of steam when the water is low, but permitting the water to flow out. This form, of ample size, may be easily placed in boilers already set up to which access is diifieult, affording a means of relief in extreme cases where the use of a single separator in a pipe would fail.

The terms upper and lower applied to the two chambers are merely relative, as the separator may be arranged in any suitable position.

The action of my separator is to permit the saturated steam under pressure to enter the inlet, where it is divided by-the knife-edges into separate streams and by the form of the inlet-passages permitted to flow forwardly in a changed direction, but with such easy turns as not to impede its flow, giving all the sep-- arate streams a whirling motion substantially in a horizontal plane, which whirling motion is greater than the velocity at the inlet, thus throwing off the suspended moisture to the outer surface of the chamber, where it flows down and around the dividing-plate to the lower chamber, whence it cannot return, while the dry steam is withdrawn from the center. All danger of retrograde movement common to separators is avoided.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a steam-separator, the combination with a shell, of an adjustable dividing-plate dividing the shell into a whirling and a still chamber, said chambers provided respectively with a steam-inlet and a water-outlet, of a defleeting-plate arranged in the whirling chamber adjacent to the inlet to turn the inflowing steam and to impart to it a whirling movement within the chamber, and a steam-outlet pipe from the whirling chamber having its mouth arranged adjacent to the deflectingplate.
